The NUF500: inspired by our body's own purification process.

Wondering how sources containing dangerous pathogens like bacteria, protozoa, and viruses can be collected and processed into safe drinkable water? The NUF500 utilizes repurposed, sanitized dialysis filters composed of polysulfone fibers — the same technologies used to remove impurities from the bodies of those suffering from kidney disease.

Our system’s mechanics are fairly straightforward. Contaminated water is forced through the filter either by hand pump or through a gravity feed system, producing approximately 126 gallons of purified water per hour.

  • Functioning parts: pump handle

  • Passive parts: 8 repurposed, sterilized hemodialysis filters and a pump diaphragm

  • Filtered substances: all components larger than 0.003 microns: suspended solids, bacteria, viruses (at 6-7 LOG rejection rate); organic matter bigger than 0.003 microns.

  • Pure water production/hour/device pumped manually: 8 liters/minute. Gravity-driven systems produce about half that rate.
